Reboot is always required to use internet. - Samsung Galaxy Note 9 Questions & Answers

This is very inconvenient. If I disconnect from WiFi or LTE, then reconnect, apps do not detect the netwoork unless I reboot first. Has anyone experienced this problem or have a solution?

Have you tried changing the Wi-Fi band on your router ?

Never thought of doing that. I don't think that would be a complete solution though, because on LTE the issue still exists; it is not just a problem on WiFi.

Are you using some extreme power saving options/solutions/aps etc etc ?

Change wifi to 4G and try again.

Last nite I installed the OTA update of android 9. Since then the problems have been non existant. I will continue to update this post, and try all the tips I have been offered, if the problem returns.

I found the source of the problem. The VPN I use was preventing the apps from accessing the Internet.

try to clear cache and dalvik cache in xrecovery
Wifi dying after a period of time.
I have a similar issue with my X8.
The Wifi works fine for a while (longest so far has been about a month) and then it just stops working. It picks up no signal what so ever from anywhere (my home router, which is about a metre away, is currently "Not in Range").
I've tried multiple versions of Android 2.2 from XDA and am now running 2.3 from the following link: http://forum.xda-developers.com/showthread.php?t=1109563
The only way i've found to bring back the Wifi is to do a FULL restore (system, data, cache, everything). I've done abt 6 restores since i started using custom ROM's about 4 months back and am in the situation where i have to do another one now. This is getting EXTREMELY irritating and I would very much appreciate it if someone could give me a solution for this.
Also, I have a lot of trouble connecting to the internet at my uni. This has been an issue from the very beginning on the X8, even before using custom ROMs. It connects the first time and then refuses to connect a second time. To connect again i have to forget the connection and start again. I don't know to describe the Wifi type but the instructions for connecting to it are in the following link http://uqconnect.net/helpdesk/wireless/eduroam/android/.
Thanks in advance
have this problem too. when i was on GDXv007 was fine then when it update to v008 i cant connect to wifi anymore.just keeps saying "obtaining ip addrees" then reboots. HEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPPPPP!

Blind wifi-help please

I own a Note 3 N900A ATT and it will not connect to any network or see them ´, it seems to be blind.
My phone is not rooted yet, does it have anything to do with it?
Help
You do not have to be rooted to connect to WiFi. You might have to manually connect to Wi-Fi or do a factory reset.

Or you might have a phone with a bad wifi radio.
If you have a wifi router running in your house and you turn wifi on (on the phone), you should see the signal from the router within 5 seconds.
(Of course if there are no wifi routers in the vicinity you won't see any signals. You have to provide the wifi signal, the carrier doesn't. Some people think it just comes with the phone service.)

Do you have wireless internet? Is the WiFi on your phone actually turned on?
I have this problem too. Glad to see you are unrooted and stock. I had deleted many .apk's and thought it was something I did.
Just get an app from the play store to fix it for the time being.

thanx i did a factory reset and it started "seeing" all networks available :good:
wifi
Factory reset is a pain on the neck, I solved this issue by turning flight mode on, the restarting and as the phone restarts on flight mode I turned the wifi on and it sees everything now. give it a try :fingers-crossed:

[Q] Losing data connection after losing and regaining signal

I have found that whenever my phone loses signal and then regains it, I have no data connection until I restart the phone. Even toggling airplane mode or manual signal search does not restore data. I have tried disabling 4G but that doesn't make any difference. I also don't have WiFi on as I never use it.
Does anyone else have this same problem and know a solution? It is extremely frustrating having to restart my phone up to 5 times a day and not receive emails etc.
I had more or less the same. What helped in my case was adding the apn of my provider manually instead of letting the network and phone handle it.

this can cause by network or firmware bug
you can manually add APN if system delete it then repair Firmware by PC Companion

I have the same issue.
Have you managed to resolve it yet?

Not yet. I have tried deleting the apn end adding it again myself but it's the same.

my problem may be slightly different in that I could not connect to Internet when out of wifi range unless I did a restart.Resolved by switching off stamina modes.

It works for me. Next week the Z3C will be updated to Lollipop. Let's hope it will solve this bug.

I was having issues when connected to my 2.4ghz network. My phone would randomly drop connection. Since connecting it to my 5ghz network, I've had no issues at all.

Some android apps causing this issue ! Find it and remove it.
Hi, I would suggest to remove your WiFi connection from your phone, restart it twice and reinstall it, including network name and password. Maybe that will solve your problem. Regards, kuzibri
Do you have this option enabled?

I don't have this option :-/
Did you ever find a fix for this? I'm always forgetting to turn it back on, and using loads of mobile data.
This problem might casusing due to some application which is conflecting with wifi settings. advice to re install the applications and then test. Factory reset can be done after this step. Thanks

Thanks for the replies. But these solutions seem to be for a different issue, they have the WiFi randomly disconnecting. The issue I have, is the WiFi turning off, as in the WiFi toggle is turned off, it connects fine and is stable when in range. But when I leave range the toggle changes to off. I'd a assume it's either a bug, or a battery saving feature, but regardless I don't want to have to toggle the WiFi back on everytime I come into range of my WiFi.

I would try it because sometimes different issues have the same solution.
